My NC Friend was not content with almost all of his power bill covered. He has an electric welder and when he has a project going his monthly bill is around the $100 mark. So he wanted a second inverter and a third solar panel array. I pointed out his garage roof and since he now has roof install experience, he said he could do it. He has the connex XW6848 times 2, a stacked pair. I helped him set his network unit numbers to be different and set up the Master slave relationship. I visited the other day to drop off 5 ea 14 ft rails he needed for the roof mount. I always order the rails in a large qty bundle to save freight, then use off the inventory until it is depleted. The long skinny rails cost a lot to ship. He is adding an MPPT 60-150 charge controller and 9ea 400 watt panels. 400 x 9 = 3600 which is just what the mppt60-150 is rated for. I told him he would never see 3600 watts out of his new array unless it was very cold with snow on the ground and the panels clear of snow. Then due to the reflection from the snow he might see 3600 watts. I told him he would see more like 2500 watts and occasionally a little more. When complete he will be free of paying the power company anything. The excess acquired in the Summer time should be available to use up in the Winter. Solar panels are on back order and he should get them in another two weeks or so. I will probably go back up there again in a few weeks in the camper and spend a couple days getting it all going.
